Initially as a child Ayu was kind and friendly. As the oldest girl in Ideal, she was looked up to by the other girls as an older-sister. Indeed she loved and cared for them so much that she chose herself to be removed from the special experiment that was presumably help them become Level 5s instead of choosing anybody else.[2] When she met Yuuri Senya, she felt sorry and pity for her, and was lectured by her and telling her to treat her normally, leading to learning a lesson in not assuming how other people felt. Due to not being saved by Touma in contrast to Shokuhou Misaki, who was saved by him and was also chosen over her to become a Level 5, Ayu bears an immense grudge against Shokuhou Misaki, to the extent that she wishes to steal the happy memories that Misaki has of him for her and her alone.

A Certain Magical Index
Academy City, Japan, is at the forefront of science. Besides being 30 years ahead of the world technologically, more than three-fourths of this peculiar city's population consists of students developing their psychic abilities as espers in various institutions. Among these students is Touma Kamijou, a high school boy with the lowest psychic rank of zero, but with a mysterious power no scientist can understand: "Imagine Breaker," which allows him to negate other supernatural abilities. This, however, doesn't affect Kamijou's life in the least as he plays his role as a regular teenager; that is, until he meets the strange Index Librorum Prohibitorum, a young girl who has memorized the entire forbidden grimoires, and now a dangerous organization is hunting Index down. With several magicians looking to harm the girl, Kamijou will defend his new companion at all costs as he discovers a strange new realm of the supernatural.

A Certain Scientific Railgun
The student-filled Academy City is at the forefront of scientific advancement and home to the esper development program. The seven "Level 5" espers are the most powerful in Academy City, and ranked third among them is middle schooler Mikoto Misaka, an electricity manipulator known as "The Railgun." When strange incidents begin occurring throughout the city, she finds each crime to be connected to the elusive "Level Upper," a legendary device that allegedly increases the esper level of its user. As the situation escalates, it becomes apparent that there is more to the Level Upper than meets the eye, and that Academy City may be a far more twisted place than the glamorous utopia it appears to be. Toaru Kagaku no Railgun focuses on Mikoto and her friends—and the dangerous situations they find themselves in—as they get caught up in the matter of the Level Upper. As Mikoto says, "There's never a dull moment in this city."
